Research
The Keefer group’s general paradigm is to theoretically design and predict novel means to measure and manipulate molecular motion with light.
Quantum Optimal Control
We tailor the temporal and spectral profiles of laser pulses using quantum optimal control theory. This allows us to steer molecular motions into desired pathways and prepare defined quantum states of the molecular wavefunction. In addition, we pioneer pulse shaping for the selectively enhance spectroscopic signatures, which is the primary thesis of our ERC Starting Grant QuantXS.
